TUDOR is introducing a bold new version of its popular model, the Black Bay Fifty-Eight, in 18 carat yellow gold with an open case back. This is a first for both in a TUDOR divers’ watch.
The name Black Bay Fifty-Eight is a reference to 1958, the year in which the first TUDOR divers’ watch waterproof to 200 metres (660 ft), reference 7924 or “Big Crown”, was introduced. Among other aesthetic nods to this historic watch, this model offers a case 39 mm in diameter in keeping with the characteristic proportions of the 1950s.
The matt 18 ct yellow gold of the Black Bay Fifty-Eight 18K is emphasised by the elegant combination of dial and bezel, which are a rich “golden green” in tone with matt gold details. The “Snowflake” hands are in 18 ct yellow gold, as are the appliqués of the hour markers.
The Manufacture Calibre MT5400, which powers the Black Bay Fifty-Eight 18K, displays hour, minute and second functions. It has the finish typical of TUDOR Manufacture Calibres: its rotor in tungsten monobloc is openwork and satin-brushed with sand-blasted details, and its bridges and mainplate have alternate sand-blasted, polished surfaces and laser decorations.
